Title RANKING DMUS WITH FUZZY DATA BY L2-NORM Type of Research Article Keywords Fuzzy DEA, DMU, Fuzzy Input-output Abstract This paper develops DEA models using imprecise data represented by fuzzy sets. By a metric distance on interval and fuzzy numbers, we introduce the approach to solve the fuzzy CCR model (FCCR) and ranking of DMUs with fuzzy data.
